LOU C. DASHNER AND HENRY E. JACOBS ASSIGNORS OF ONE-THIRD TO ALONZOVIRGINIA.

NUT-LOCK.

Application filed June 26, 1912.

To (ZZZ whom it may cone-em.-

Be it known that we, LOU C. DASHNER and HENRY E. JACOBS, citizens of theUnited States, residing at Point Pleasant, in the county of Mason andState of lVest Virginia, have invented new and useful Improvements inNut-Locks, of which the following is a specification.

This invention relates to the class of nut locks.

Heretofore the utility of nut locks of different types has beenquestioned by reason of their failure to perform the function to whichthey are adapted. hen nut locks of the pawl and ratchet type areprovided in connection with different structures it has been found thatthe pivot point of the pawl is often broken by the strain which isexerted thereupon and it is our object to overcome this difficulty andprovide means whereby the strain which is exerted upon the pawl is notdisposed entirely upon the pivot point.

-With the above and other objects in view our invention consists in suchdetails of construction and in the arrangement and combination of partsas will be hereinafter more fully described and specifically pointed outin the appended claims.

In describing our invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of our invention shown applied to anordinary rail joint. Fig. 2 is a longitudinal sectional view on line 22of Fig. 1. Fig. 3 is a vertical sectional view on line 3-3 of Fig. 1,and Fig. 4: is a detail view.

The rails and the fish plates 2 constitute an ordinary rail joint and inconnection with which our invention has been illustrated. A bolt 3extends through the fish plates and the web of the rails and hasoperative thereon, as is well known, a nut 4. Before the nut is screwedupon the bolt, the body portion of our invention is disposed in place.This body portion consists of a member 5 which has its lower end bent atright angles thereto as shown at 6 and performs the subsidiary functionof a washer. A washer 7 which has teeth 8 formed thereon is thendisposed in place, the said washer Specification of Letters Patent.

carrying a collar 9 which receives the nut, as is clearly shown. By theprovision of the collar it is apparent that the nut cannot be rotatedwithout transmitting motion to the washer 7.

The pawl which is devised consists of a body portion 10 which is pivotedto the member 5 as shown at 11 and which has a portion thereof extendingupwardly as at 12 so as to form a tongue for engagement with the teeth8. The lower edge of the pawl is normally disposed in parallel relationto the bent portion 6 of the member 5. However, when the movement of thenut is reversed the pawl will be forced through the medium of the washer7 into engagement with the bent portion, thereby exerting more pressurethereupon than upon the pivot point.

From the foregoing, it will be readily realized that the nut which wehave devised consists of but a few simple parts which can bemanufactured at a very low cost and sold at a minimum. It is alsothought that the advantages and novel features of our device will bereadily appreciated.

Having thus fully described our invention, what we claim as new anddesire to secure by Letters Patent, is

1. The combination with a rail joint, comprising rails and fish platessecured thereto, of a bolt extending through said fish plates and saidrails, a member disposed about said bolt and having its under side bentat right angles to the body portion thereof, a washer disposed upon saidbolt, said washer being provided with a squared collar, a nut carried bythe said collar and rotatable with said washer, teeth formed upon saidwasher, a pawl pivoted upon said member and having a portion thereof inengagement with said bent portion, a portion of said pawl adapted toengage said teeth, whereby the reverse movement of said washer and saidnut is prevented, for the purpose described.

2. The combination with a rail joint, comprising rails and fish platesattached thereto, of a bolt extending through said rails and said fishplates, a member disposed about said bolt and having its under side bentat right angles to the body portion thereof, a washer disposed upon saidbolt and in engagement with said member, said washer being provided witha squared collar, a nut disposed within said collar and operative mentof said washer is prevented, for the upon said bolt, said nut beingrotatable with purpose described.
